Beit'kncmfrr that-TGEORGQBERQN; Uli-"Washingtorqip'the eounty-ofFranli'lng--and State of'Missouri, have invented n. new and usefulImproved B'Olt and Spring for Shears, of' which thefollowingvis afull,clear, und exact description, reference being had to the annexeddrawing, hinking a part ofthis specification, in whieh-a Figure 1represents u pair of ehem-shaving iny invention. `Figure 2 represents'a.detached-view of my invention. Similarletters indicate like parte, A' yThe object of theinventon'is to errungen-spring foropening shears insueha. manner-'that it will be simple, .flur-nble, and Vnoi: interfere withthe hand when using the 'sl'ienrsnV n In shenrs, A, of nydesired form, Imnke the bolt b, iig. 2, somewhat larger than usual,with a thread,`c, onone end,`a.nd over the head, dLI plaise a'brond cap, 'e,rigs. 1 and 2,all, however, melde in onepiece. In t'lle side of the bolt, near theend, is a. slot, h, made to receive n eorrespOnding-stud in the underblade Ic of the shea-rs. The'bolt being in place, -it issecured hy uno'rilinnry nut. Through 11n-opening in the head d is passed ncoibepring, o, figs. l'and 2, which is wound around the head, itsotherend being curved so as toi-est against the shoulder n on the upperblade s of the shears when the same are opened. 'It is evident that assoon as the V pressure used to bring the blades Atogether is removed,the tension of the spring will canse them te open nr once, the slot in`the bolt and its tud preventing thebolb from .turning Ol" coursetliisspring and boli: maybe' appliedto oflle instrument-s than shears, infact lo all which have the scissors-movement; consequently I dO- `-notlimit myself to'his purtipulnr instrumen-in the use of my invention.

What I clairnas my invention, and desire to seeureby Let'ltersPntent,is- The slotted-bolt l, wlith'ite cnpe, spring o, and shoulder n, all incombination; when rrangerl in relationto Veavelx other and the bladesof4 the shears, substantially es nndfor'the purpose specilierl.
